Hi. My husband and I purchased a propeller at a garage sale full of vintage items, yesterday. It is 54 inches long and I believe the wood is maple. It has a coating on the back of it (and a motor the guy attached to it!) My dad (an 87 year old former pilot) says he is pretty sure it is authentic and not a repro. Does anyone have any thoughts on age/related plane? It has no markings on it, except for 54 and 27. Thanks for your help!

I think it is an ultralight propeller that has been re-purposed at some point. Note the filled bolt holes, particularly the sequence of four holes in a smaller radius, along with two sets of 6 holes. It may have originally be a reproduction display prop but I think the ultralight usage is more likely.
It would not be an "authentic" prop for a certificated aircraft of any kind, as it would have design and serial numbers stamped around the hub. -
Thank you very much! That makes sense from what I've been researching. As far as this being a reproduction, it had wear on it and I wasn't sure why there would be the dark coating on the back of it if it was just made for display.Originally posted by Dbahnson View PostComment

That, plus there's a reason it is drilled for several different bolt hole circles, which wouldn't likely be done with a display prop.Originally posted by JMAviator View PostComment
